2. 1. A novel implantable ultra-flexible brain machine interface. Manufacturing and initial characterisations

   Author : Fotios Tsanakalis; Neuronano Research Center (NRC); []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain-Machine Interfaces; BMIs; Neural Interfaces; Electrodes;

   Abstract : This thesis describes for the very first time the development of a miniaturized neural interface which is flexible in three dimensions (3D) to enable it to follow the brain movements with minimal dislocation. Both the design rationale and the material choice for the electrodes aim to develop interfaces that minimize the damage and/or the irritation of the tissue during and after the implantation.

4. 2. Malnutrition and obesity among older adults, assessed by Mini Nutritional Assessment and the body mass index, respectively : prevalence and associations with mortality and urinary tract infection

   Author : Maria Burman; Birgitta Olofsson; Yngve Gustafson; Peter Nordström; Tommy Cederholm; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Malnutrition; obesity; underweight; Mini Nutritional Assessment; Body Mass Index; older adults; very old; community dwelling; residential care facilities; mortality; urinary tract infection; Geriatrics; geriatrik; näringslära; Nutrition;

   Abstract : INTRODUCTION: Malnutrition and obesity are health concerns among older (aged ≥ 65 years) adults, but the combination of them have not been studied thoroughly nor have they been thoroughly investigated in very old (aged ≥ 85 years) adults. The aims of this thesis were to investigate the prevalence, trends in prevalence and associations with mortality of malnutrition and obesity, assessed by Mini Nutritional Assessment (MNA) and the body mass index (BMI), respectively, and to examine the combined effects of these conditions on mortality.

5. 3. Stimulating the Brain : Ethical Perspectives on Deep Brain Stimulation & Nano Scaled Brain Machine Interfaces

   Author : Veronica Johansson; Centrum för teologi och religionsvetenskap; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : This thesis addresses some of the ethical concerns raised by connecting man and machine through so called Brain-Machine Interfaces, BMIs, elaborate brain implants that may both further our knowledge of the brain and alleviate neurological dysfunction and impairments. The primary foci have been to address urgent and prominent concerns elicited by BMIs; to critically evaluate arguments relevant to an ethical analysis of Deep Brain Stimulation, DBS; and to address and develop ignored or underrepresented perspectives of importance in an ethical analysis of DBS.

6. 4. Signal Modeling and Data Reduction for Wireless Brain-Machine Interfaces

   Author : Palmi Thor Thorbergsson; Institutionen för elektro- och informationsteknik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Extracellular neural recordings; wireless brain-machine interfaces; signal modeling; data reduction; compression;

   Abstract : Brain-machine interfaces (BMIs) provide a uni- or bidirectional communication link between the central nervous system and the outside world. This link facilitates the studying of neuronal mechanisms underlying behavior as well as the treatment of neurological disease. READ MORE

7. 5. A Process View of Business Model Innovation

   Author : Sara Fallahi; Joakim Björkdahl; Stefan Haefliger; RISE; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cognitive search; ambidexterity; process; experiential learning; innovation; resource based view; business model; problem;

   Abstract : In an era of globalization, cross-fertilization of technologies and industries, and changing markets, firms are introducing new ways of creating or capturing value through Business Model Innovations (BMI). In recent years, BMI has become one of the priorities of practitioners, and has attracted the interest of scholars since product or process innovations on their own are perceived insufficient in the current internet era when other sources of competitive advantage are being needed.
